Title: Variable venturi type carburetor
Inventor: ITOU TAKAAKI
IPC: F02M7/17
Filed: 1982-09-03
Abstract: PURPOSE:To accelerate the reduction of size of fuel particle by increasing the amount of displacement of a suction piston in idling and in highly-loaded state and relatively reducing the amount of said displacement in light loaded state. CONSTITUTION:The operation of a negative-pressure control valve 20 is controlled by the negative-pressure action of a port 26 formed on the upstream side of a throttle valve 5. The spring force of a spring 24 of the negative-pressure control valve 20 is balanced in a proper state with the negative pressure in the port 26. Therefore, a valve body 23 shuts-off a bypass air passage which is constituted of a pipe 19 and communicates to a suction chamber 10, in idling or in highly loaded state where the negative pressure of the port 26 is small, and the atmospheric pressure is introduced into the suction chamber 10 through the pipe 19 from the atmospheric pressure chamber 10 in light loaded state where the port negative-pressure is large. Accordingly, the negative pressure in the suction chamber 10 reduces, and the amount of displacement of a suction piston 2 is relatively reduced, and the load on a venturi is increased, and reduction of size of fuel particle is accelerated.

Abstract: PURPOSE:To achieve control while cooperating among the systems of amount of control when recovering one system by comparing the output values of a control advance angle priority circuit of a self system and another system and then releasing the break when the difference is within a certain value. CONSTITUTION:'1' is output by detecting abnormality when a control device 100AA fails in an abnormality detection circuit 31AA but it is also output to another system and the output of a flip-flop circuit 32AA is set when the output of the abnormality detection circuit 31AA is in '1' and a switch 37AA is operated. Then, only a control advance angle priority circuit 28AB is input to a selection circuit 50AA but the output value of the control advance angle priority circuit 28AB is selected since two input values are equal. Also, a comparison circuit 36AA compares the output value of a control advance angle priority circuit 28AA with that of 28AB and then outputs '1' when the difference is within a certain value. A similar operation is made even if the abnormality detection circuit 31AB of another system operates.

Title: Magnetic recording material
Inventor: TOMONO KUNISABURO
IPC: H01F10/20
Filed: 1984-07-23
Abstract: PURPOSE:To obtain a magnetic recording material which has small secular change of magnetic characteristics and satisfies the characteristics required for vertical magnetic recording and optical magnetic recording by specifying a composition consisting of cobalt oxide, iron oxide and aluminium oxide. CONSTITUTION:A material consisting of cobalt oxide, iron oxide and aluminium oxide and having a composition shown by a general formula Cox(Fe1-yAly)3-x O4 (wherein, 0<x<1, y<=0.75) is used. Co ferrite cannot be made by x=0 and a material which has required characteristics cannot be obtained. High coercive force cannot be obtained by x>=1. If (y) exceeds 0.75, Al becomes excessive and the reproducing output of a magnetic head and magneto-optical effect cannot sufficiently be obtained. For example, a film like magnetic recording material is formed by cooling in a magnetic field using film forming means such as sputtering, vacuum deposition, ion plating or non-electrolytic plating. This enables to obtain vertical anisotropy, while a magnetic recording medium having high coercive force, a flow Curie temperature and great Kerr effect or Faraday effect can be obtained.
